Contact is closed, water inlet pipe is not connected with outlet pipe；During piston moves up and down in the spool chamber, in addition to damping hole, outlet pipe its
The chamber that it is partly located above piston with spool chamber is not connected all the time.
For the ease of the setting of damping hole, damper tube is provided between outlet pipe described in the utility model and spool chamber,
Described damping hole is damping pipe orifice, the axis of described outlet pipe and the diameter parallel of spool chamber.
Moved up and down to ensure that piston is stable in valve body cavity, valve element described in the utility model also includes guide post
And fairlead, fairlead one end is threadedly coupled with plug, and guide post one end is fixedly connected with the piston, and other end sliding plug is to leading
To in set, described spring housing is on guide post and fairlead.
In order to current filtration, valve element described in the utility model also includes filter mantle, and filter mantle is cylinder, cylinder
Filter opening is densely covered with body, the upper end of filter mantle is threadedly coupled with the lower end of piston, when described piston movement to lower limit position
When, the part that filter mantle is in outside piston is completely in water inlet pipe, when described piston movement is to upper extreme position, mistake
The lower end of filter bowl is in water inlet pipe, has filter opening to be communicated with outlet pipe on filter mantle.
The beneficial effects of the invention are as follows：The utility model is provided with damper tube between valve body cavity and outlet pipe, when too urgent
Current when passing through valve body, because the water in damper tube will not flow out from damping hole quickly, piston slowly opens, it is to avoid mistake
Anxious water impact valve element throws open, the damage to valve element；The valve seat being adapted is provided with piston and water inlet pipe, works as valve body
During not water flowing, upper valve base and lower valve base closing contact prevent current from flowing backwards.The utility model can play its resistance to High-Pressure Water
Buddhist nun's guide effect, can both avoid too urgent water impact valve body, moreover it is possible to prevent current from flowing backwards, and play a part of two-sided guiding.

Specific embodiment
Two-sided guiding check valve as shown in Figure 1, including valve body and valve element, valve body include water inlet pipe 8, outlet pipe 9 and valve
Core cavity 11, the upper end of water inlet pipe 8 is provided with lower valve base 8-1, and water inlet pipe 8 is connected with the lower end of spool chamber 11, the lower end of outlet pipe 9 with
The lower end connection of spool chamber 11, valve element includes plug 1, fairlead 2, spring 3, guide post 4, piston 5, sealing ring 6, filter mantle 7,
Piston 5 is arranged in spool chamber 11, and the lower end of piston 5 is provided with the upper valve base 5-1 being engaged with described lower valve base 8-1, close
Seal 6 is arranged on piston 5, and plug 1 is connected with the threaded upper ends of spool chamber 11, and the one end of fairlead 2 is threadedly coupled with plug 1,
One end of guide post 4 is fixedly connected with piston 5, and in the other end sliding plug of guide post 4 to fairlead 2, spring 3 is enclosed within guiding
On bar 4 and fairlead 2, spring 3 is located between plug 1 and piston 5, and damper tube 10 is provided between outlet pipe 9 and spool chamber 11,
The one end of damper tube 10 is connected with outlet pipe 9, and the other end of damper tube 10 is connected and under plug 1 with the upper end of spool chamber 11
Side, the axis of outlet pipe 9 and the diameter parallel of valve body cavity 11, filter mantle 7 is cylinder, and filter opening is densely covered with cylinder, filter mantle 7
Upper end is threadedly coupled with the lower end of piston 5, when described piston 5 moves to lower limit position, filter mantle 7 be in piston 5 it
Outer part is completely in water inlet pipe 8, when described piston 5 moves to upper extreme position, the lower end of filter mantle 7 be in into
In water pipe 8, there is filter opening to be communicated with outlet pipe 9 on filter mantle 7.
Operation principle：Water is full of in spool chamber 11, as shown in figure 1, when valve body not water flowing, the clamping piston 5 of spring 3, on
Valve seat 5-1 and lower valve base 8-1 closing contacts, water inlet pipe 8 are not connected with outlet pipe 9；As shown in Fig. 2 when valve body water flowing, it is too urgent
Water impact piston 5, piston 5 compression spool chamber 11 in water entered into outlet pipe 9 from damper tube 10, due to damper tube 10
Endoporus is tiny, the water in spool chamber 11 will not be discharged quickly, and piston 5 is slowly opened, it is to avoid too urgent current are caused to valve element
Damage, current are entered into filter mantle 7 from water inlet pipe 8, then enter into outlet pipe 9 by the aperture in filter mantle 7, are finally flowed out
Valve body；When valve body not water flowing, the water that spring 3 pushes residual in piston 5, outlet pipe 9 is inhaled into valve element by damper tube 10
In chamber 11, because residual water will not be inhaled into quickly, piston 5 slowly declines, until upper valve base 5-1 and lower valve base 8-1 again
It is in sealing contact, it is again filled with water in spool chamber 11.
